How loud are these pumps usually? I had one put in last week by a local rotary mechanic. When I start the car the sound is not noticeable for about 45 min, then I start to hear it, and by an hour it's loud and annoying. You can hear it a good distance away outside the car too.
I made this youtube clip. First the camera is in the drivers seat, then I put it over the back seat near the pump. You can hear the tone change a lot when I use the window switches.

You would hear mine. The volume is about same as the engine idling from within the car. In a parking lot you can easily hear it humming from 30+ feet away. I assume since it's quiet for the first 45 min that it should always be relatively quiet, so I can't stop thinking something must be wrong with it, or it's a knock-off. It's a well known shop but idk where they source their pumps from.

Original Turbo 'd Auto !!
I can hear mine after the car is started. It's a very faint whine and can not be heard outside the car.
My 1st unit ate itself with less than an hour on it. Ray was very kind and rma'ed it out for me.
Thanks Ray !

Dunno if this has been answered and cant find anything when i search but is anyone else having problems with the walbro sucking more fuel from the right side of the tank than the left?
its stuffing up my fuel gauge making it say i have half a tank left when ive already travelled over 300kms, is there a solution for this or did i just install the pump wrong?

yep---- there is a wire that crosses the tank that can get tangled in the level sensor stuff which will cause that exact thing. It happened to me. Just take the pump out and look in it toward the passenger side and you can see it.
Has anyone installed a fuel pressure gauge?

The range is 55 to 65 PSI with a warning set at 45 PSI, which dumps the wastegate when crossed.
When the car starts, there is a "spike" to 75 PSI and it immediately settles to 65 PSI. It doesn't vary all that much, but it is affected by altitude and barometric pressure. I don't know if that is the sender (probably) or the pump head (probably not).
Generally, when I go WOT, the fuel pressure drops about 2 PSI and holds there.
Turning has no effect at all, even when the tank is nearly empty.
An interesting side effect of the pump upgrade is that I can truly run the tank dry.
I filled up yesterday and she took over 15 gallons.
